This is the Hitec Optima 7 - 7Ch 2.4GHz Receiver. The Optima 2.4GHz
line of receivers feature Hitec's exclusive BODA receiver technology.
Independent tests have proven that the single BODA system in Hitec's 6
and 7 channel systems is equal to or better than a dual antenna system. The
Optima line of receivers and Spectra 2.4GHz module have full telemetry
capabilities with built in low receiver battery warning. Additional
telemetry capabilities can be added using optional sensors for display
in the Aurora 9 or with Hitec's PC based Telemetry Monitoring System.
